This is from another experience user of both program :

"If you follow skisouth's advice and run Revit out of the box, and ArchiCAD out of the box, I think you will find Revit to be superior. ArchiCAD has an open API, and at least a few 'add-on' programs are needed to make it do some simple things, like stairs. (ArchiStair is free, but its still an add-on, and thus must keep up with the development cycle. Will ArchiStair work with ArchiCAD 9, soon to be released?) Rendering in ArchiCAD is done via an add-on. In some cases, add-ons are good because they allow third party developers to create programs that work woth ArchiCAD, but for the most part Revit is 'complete' out of the box and really hasn't required any outside development.

ArchicAD is developed to run on both PC's and Macs, which many people like. It also means the programmers have to do double-duty and make sure the code works the same on both platforms. Some might say that this could slow down the development cycle. If your office runs Macs, well then maybe ArchiCAD is for you. If you are on PC's, I'd lean towards Revit.

Revit has the financial backing of Autodesk, one of the largest software companies in the industry. Being an Autodesk product assures continued compatibility with other Autodesk software, including AutoCAD, and maybe more in the future. AutoCAD DWG compatibility is absolutely essential.

Revit is easy to learn and use, as you have already discovered. It is very intuitive, and is programmed to work how Architects work, because it has Architects developing it.

ArchiCAD has over 20 years of experience in the 3D CAD/BIM market. Revit has 5. ArchiCAD should be widely accepted and an industry standard by now, shouldn't it? Revit in my opinion has created more of a buzz in 5 years, and keeps getting better with every release.

Building content in ArchiCAD will required learning a programming language called GDL.. Yes, add-on programs will help build the code for you, but to truely harness the power of ArchicAD, you will need to learn GDL. Are you a programming firm, or an architectural firm?

Go over to http://archicad-talk.graphisoft.com/ and read their forums. You will find out plenty about what ArchiCAD can and can't do. Just recently, there was a thread discussing the procedure to put a perspective view on a sheet in PlotMaker (another separate program to lay out sheets). It involved several steps to do....in Revit, drag the perspective on the sheet. Done.

Revit has bi-directional parametrics. You can make a change in a schedule, and the model will update.

ArchiCAD doesn't assure full drawing coordination. In ArchiCAD, the user can 'break' the links to views, so they are no longer 'live' views of the model. If a change is made to the model, the view wont update. This leads to coordination errors. In Revit, you will never have to second guess that a detail callout is filled out correctly.

There is so much more, and I will try to add them here as I think of them. There are many Revit users here that have a lot of ArchiCAD experience before coming to Revit, so hopefully they will add to this. I have zero ArchiCAD experience, except what I have learn from their newsgroup. If I have mis-stated anything here about ArchiCAD, I will gladly welcome corrections.

I have to add that ofcourse this guy is bias LOL.. he is after all Revit tips and trick forum manager...

... but some of his points ARE valid.. really upto you to try both to find out which is better...
